Presentation

minimal degreeμ(G) = 26
transitive degreeμt(G) = 128

A minimal faithful permutation representation — 6 generators on 26 points:

(11,12)(13,15)(14,17)(16,18)(19,20)(21,25)(22,23)(24,26);(11,13,14,18)(12,15,17,16)(19,21)(20,24)(22,25)(23,26);(4,6)(8,10)(11,13)(12,16)(14,18)(15,17)(19,22,23,20)(21,25,26,24);(7,8)(9,10);(3,4)(5,6)(7,8)(9,10)(11,12)(13,15)(14,17)(16,18)(19,21)(20,25)(22,24)(23,26);(1,2)

Past the SmallGroups library coverage — no SmallGroups id. Construct it from a minimal faithful permutation representation:
